Next week, bookstores will be stocked with copies of “Salinger,” a big, fat, 700-page volume of biographical information, letters, photos and more, all in the service of providing an exhaustively detailed portrait of the famously reclusive novelist J.D. Salinger.

In it, there are notes and drawings from Joyce Maynard (who wrote extensively about her relationship with Salinger, which started when she was 18 and he was 53), letters from Mark David Chapman (John Lennon’s killer, who was found at the scene of the murder reading Salinger’s “Catcher in the Rye”), and details from Salinger’s tour during World War II (he landed at Utah Beach on D-Day in June, 1944).
